No idea whats the best way to do and what in detail you want to achieve,
but before others reply here, you can maybe start with something like this:
intTheInt = None
def checkIfStringCanBeAnInteger(strWithInt):
global intTheInt
try:
intTheInt = int(strWithInt)
if(type(intTheInt)==type(1)):
return True
except:
return False
#:def
lstTestCases = [
'123', '789' , 'no', '1is2'
]
for strWithInt in lstTestCases:
intTheInt = None
if checkIfStringCanBeAnInteger(strWithInt):
print '"'+strWithInt+'"', ' is an integer', intTheInt
else:
print '"'+strWithInt+'"', ' is NOT an integer'
